Henry left Southampton on the ship 'Columbia' on 16 May 1954, heading for Montreal, and intending to reside permanently in Canada. He gave his address as 106 Muirshiel Crescent, Glasgow, and his occupation as mech. leather worker. There were no other Synnots with Henry on the ship.

There was another transatlantic crossing later that year - on 16 Oct 1954 Henry D. Synnot arrived in New York from Glasgow on the 'Egidia'. There is no age given for Henry. He gave a Canadian address - 244 Benson Ave, Toronto 10, Ontario. Perhaps he made a return trip back to Scotland after his initial arrival in Canada in May - or, more likely, this is another Henry D. Synnot, possibly his son. There are no other Synnots on the passenger list for this trip.
